Break immunologic tolerance with the non-natural immunogen
A major challenge in the modern medicine treatment is to develop effective ways, and the immunogenicity that strengthens the weak immunogenicity exogenous antigen of specificity is as obtaining neutralizing antibody, and perhaps selectivity overcomes the tolerance for autoantigen.Distinguishing self for immunology is self-tolerance with nonself process important concept, wherein mammiferous immune system to avoid autoimmune disease, mainly is because lack autoreaction B-or T-cell or inactivation takes place for autologous protein matter " tolerance ".Take multiple strategy to tackle these challenges, comprise exploitation improvement adjuvant and carrier, in antigen, introduce strong t cell epitope, fat coupling and combination-vaccine etc.Referring to for example Baldridge etc., " vaccine adjuvant: immunology and clinical principle " (Vaccine Adjuvants:Immunological and Clinical Principles.) C.J.Hackett, Harn, D.A.Jr. compiles. (Xiu Mana publishing company, New Jersey Tuo Tuowa), 235-255; Makela etc., Expert Rev Vaccines, 1 (399): 399-410 (2002); Dalum etc., Nat Biotechnol.17:666 (1999); And Restifo, Curr Opin Immunol8:658 (1996)..Shown that the rabbit Elityran with the extensive non-specific labelling of diazo compound derivative carries out immunity to rabbit, can induce the cross reacting antibody for natural Elityran.Referring to Weigle, J Exp Med121:289 (1965).Yet, be difficult to make things convenient for modification/control to solve other antigenic problem etc. to this method.Equally, the non-specific derivatization from the body cancer cell that contains the dinitro benzene group is used as vaccine (Berd in the melanomatosis people, D. (2004) " M-Vax: a kind of human cancer vaccine " (M-Vax:an autologous, hapten-modified vaccine for human cancer) from the body hapten transformation Expert Rev Vaccines3:521-527).Also can be with reference to other document (as embodiment hereinafter).
Compare with trial before, the present invention replaces a plurality of natural amino acids of work (in specific required site) with a plurality of alpha-non-natural amino acids of work (UAA) thereby creation non-natural immunogen in the target epi-position of target part (as the target part of disease association).Other or in addition, create the non-natural immunogens thereby can in the target epi-position of target part, add one or more specificity alpha-non-natural amino acid residues.Replacement and/or creation alpha-non-natural amino acid can be created one or more immunogenicities in the non-natural immunogen, the epi-position that arbitrary structures is conservative, thereby can (in object) cause that regional intensive immunne response is answered in natural target proteins confrontation at wild type (wt), as T-cell response and/or B-cell response.And as mentioned below, the cross reacting antibody that is produced for the non-natural immunogen also can have specificity to the zone of the corresponding natural target molecules that do not comprise alpha-non-natural amino acid.Vide infra.Using monoclonal antibody or chimeric medicine to break aspect the tolerance, the trial before the present invention can lead over arbitrarily, problem before need to be frequent injection and a large amount of protein.。As shown here, in some embodiments, use the serum persistency of the antibody that non-natural immunogen of the present invention produces in object that the frequency of immunostimulant is reduced.
The B cell is by free (solubility) antigen (as the non-natural immunogen) in BCR (B-cell receptor) or membrane bound immunoglobulin identification blood or the lymph.After antigen recognition, the B cell is its endocytosis, and with the form of MHC complex at its surface display antigen fragment.In a single day the B cell is activated, and grows to be memory B cell, produces justacrine antibody, in the help and the disease association target part of antigen (non-natural immunogen) origin (or corresponding), and/or help destruction to have antibody can be near the infectious target agent of epi-position.
Antigen (as the non-natural immunogen) specific T-cells is as CD4 +The T cell combines with MHC-complex fragments of peptides as the B cell display.The T cell proliferation was kept away that cytokine that discharges immune stimulatory cell proliferation and confused China then; some bud into memory cells in these activated T cells; instant protection to the target (as disease association) that originates from as anti-non-natural immunogen is provided, and the ability that causes rapider and effective secondary immune response.In the T lymphocyte proliferation assay, can measure this activity (referring to embodiment 1 and 2).
The nonsense that antibacterial, yeast or mammalian cell are corresponding specific and move the frame codon hereditism's coding surpass 50 kinds of alpha-non-natural amino acids.Referring to for example, Wang etc., Science292:498 (2001); Chin etc., Science301:964 (2003); Liu etc., Nat Methods4:239 (2007); Anderson etc., Proc Natl Acad Sci U S A101:7566 (2004); With Wang etc., Angew Chem Int Ed Engl44:34 (2004), and other list of references of this paper.These comprise melts combine and post translational modification aminoacid, fluorescence and redox active amino acids, and photoreaction and chemical reaction aminoacid.For example, the derivant with phenylalanine right-Nitrobenzol alanine (pNO 2Phe Figure 1A) mixes corresponding succinum nonsense codon in the bacterioprotein, has high fidelity and good efficiency during as the spectrum intervals probe.Referring to Tsao etc., J Am Chem Soc128:4572 (2006).Should be understood that and for example and in describing pNO has been discussed at this paper 2The use of Phe, single the limitation therewith, the present invention contain any alpha-non-natural amino acid (as, include but not limited to described in cited herein and/or this paper list of references) purposes.Hereinafter provided the out of Memory of the alpha-non-natural amino acid that can be used for the various embodiments of this paper.
Break the embodiment of immunologic tolerance with the non-natural immunogen.
Once used the nitro aryl (to compile " catalytic antibody " referring to Keinan in history as the high immunogenicity hapten Catalytic Antibodies (WV company (Wiley-VCH), Wei En Haimu (Weinheim ), 2005), 1-28), may be because the pi system of electron deficiency is tending towards Tyr and the interaction of Trp side chain common with the antagonist binding site.Since their structural similarity, the Phe → pNO of interested target part 2Phe or Tyr → pNO 2Phe sudden change (as the disease association part) can produce the immunogen that strong immunization is replied, the originate natural target part cross reaction of (corresponding) of described immunne response and immunogen.
Therefore, as shown in the Examples, use as Mus tumor necrosis factor-alpha (mTNF α) Tyr 86→ pNO 2Phe muton immune mouse produces the high titre antibody to wild type mTNF α (wt mTNF α) response, therefore can effectively protect mice antagonism lipopolysaccharide (LPS) to stimulate.
Select mTNF α to show (a plurality of) of the present invention aspect as target proteins matter because it relate to infect, the evaluation of inflammation and autoimmune phenomena clearly cytokine (referring to Vassalli, Annu Rev Immunol10:411 (1992)); And, comprise that its expression, structure, function and signal transduction mechanism further investigate for the biological property of mTNF α.Referring to for example, aforementioned Vassalli; Baeyens etc., Acta Crystallogr D Biol Crystallogr55:772 (1999); Pennica etc., Proc Natl Acad Sci U S A82:6060 (1985); Pasparakis etc., J Exp Med184:1397 (1996); Baeyens, H.L. etc., Acta Crystallogr D Biol Crystallogr53:329 (1997); And Aggarwal, Vilcek, J., volume " tumor necrosis factor: structure, function and mechanism of action " ( Tumor necrosis factors: Structure, function, and mechanism of action) (New York De Keer, 1992) (Dekker, New York, 1992), 1-587.In addition, mTNF α knock-out mice can be survived, and does not show obvious phenotypes unusual (referring to Pasparakis, the same), this shows that mice can survive in the TNF that creates antagonism He in the immunne response, this makes the inoculation animal can be used for analyzing anti-TNF alpha production of antibodies and biologic activity.And, anti-TNF alpha antibody (Knight etc., Mol Immunol30:1443 (1993); With Present etc., N Engl J Med340:1398 (1999)) and the chimeric TNF α of solubility receptor (Peppel etc., J Exp Med174:1483 (1991); With Williams etc., Immunology84:433 (1995)) has been widely used in the treatment rheumatoid arthritis.Therefore, clinical need TNF α-specificity vaccine (Dalum, the same; Spohn etc., J Immunol178:7450 (2007); Buanec etc., Proc Natl Acad Sci U S A103:19442 (2006); Capini etc., Vaccine22:3144 (2004)).Based on the trimerical X-ray crystal structure of mTNF α basis (Baeyens etc., Acta Crystallogr D Biol Crystallogr55:772 (1999); With Baeyens etc., Acta Crystallogr D Biol Crystallogr53:329 (1997)), select Tyr 86→ pNO 2MTNF α (the pNO of the single sudden change of Phe 2Phe 86MTNF α is referring to Figure 1B) immunogen of showing explanation as the present invention.Tyr 86Conservative at the mammiferous TNF camber of difference, determined that this site mutation does not influence Protein Folding or trimer forms.Tyr 86Sudden change also causes Cytotoxicly significantly losing, and this has advantage to produce when vaccine is purpose.Referring to for example, Van Ostade etc., Protein Eng7:5 (1994); Loetscher etc., J Biol Chem268:26350 (1993); With Zhang etc., J Biol Chem267:24069 (1992).
Be tested and appraised feature and persistency to the polyclone IgG antibody of anti-TNF alpha, and by the displaying wild type retinol binding protein 4 that creates antagonism, the antibody of mRBP4 (purposes that has therefore shown the oneself protein that immunologic function has nothing to do among the present invention), embodiment 2 has further showed extensive use of the present invention.What is interesting is that embodiment 2 has shown pNO 2Phe-induces and has broken self tolerance, has produced the antibody at a plurality of epi-positions of WT mTNF α, and described epi-position needn't comprise among the natural TNF α and non-natural immunogen TNF α pNO 2The zone of Phe residue correspondence.Therefore, that utilizes that non-natural immunogen of the present invention carries out that immunity can be favourable causes the expansion of immunoglobulin epi-position, is different from the main target that the epi-position of inducing epi-position becomes ongoing immunne response in view of the above.Vide infra.The epi-position that immunity is extended to the disease association target part in whole non-natural immunogen source is a kind of a kind of phenomenon that especially needs after vaccine design.The effectiveness that its a plurality of targets that can attack disease association target part can be increased reply for the enhancing of immune system ability at the target partial immunity/or intensity.
That should be understood that embodiment hereinafter shows is not only TNF α or RPB4 in the embodiment of the present invention.Describe as can be known from this paper, in non-natural TNF α and RPB4 target part, can comprise one or more any alpha-non-natural amino acids in the various embodiments.And the alpha-non-natural amino acid that occurs on this type of non-natural immunogen can be positioned at any position of immunogen inside.The alpha-non-natural amino acid that replaces natural amino acid corresponding among natural TNF α and the RBP4 can be that conserved amino acid replaces, and also can be that non-conserved amino acid replaces.Also can any method of passing through in the several different methods make up non-natural immunogenicity TNF α and RBP4.Use orthogonal translation (vide infra) conduct directly to mix the approach of alpha-non-natural amino acid to right a lot of embodiments, but also can use other directly to mix method (as external translating system, solid phase and title etc.) arbitrarily.The embodiment of this paper does not generally use translation back or chemical modification method, except with directly mix method such as orthogonal translation coupling.
The method and composition that reinforcement/enhance immunity originality is replied
From this paper embodiment and the explanation as can be known; non-natural immunogen of the present invention natural target part (as not comprising the disease relative protein white matter of alpha-non-natural amino acid) the intensive cross reacting antibody that can create antagonism is replied, thus the disease (or can be used for handling morbid state) of protectiveness antagonism target part correlation.Therefore, the present invention as the surface exposure epi-position or the T-cell epitope of disease association target part, can break the immunology self tolerance by alpha-non-natural amino acid being mixed the specificity epitope of target part interested.For example, in following reduced graph, target part (as disease association target part) comprises epi-position 1,2 and 3.The non-natural immunogen also comprises epi-position 1,2 and 3, and described epi-position derives from or corresponding (having identical sequence) target epi-position 1,2 and 3 partly.Yet the immunogenic epi-position 2 of non-natural comprises the alpha-non-natural amino acid (asterisk is represented) of the corresponding natural amino acid of replacing the target part.In the non-natural immunogen, exist alpha-non-natural amino acid to produce the cross reacting antibody (epi-position expansion) that to discern the different epi-positions of target part.For example, can produce cross reacting antibody at epi-position 1 and 3 (the not corresponding immunogenic epi-position of non-natural that comprises alpha-non-natural amino acid) and epi-position 2 (correspondence comprises the immunogenic epi-position of non-natural of alpha-non-natural amino acid).
The target part
Epi-position 1 Epi-position 2 Epi-position 3
The non-natural immunogen
Epi-position 1 Epi-position 2 * Epi-position 3
By locus specificity alpha-non-natural amino acid is mixed the defined epitope of leading interested target part and create the non-natural immunogen, thereby break the immunology self tolerance, can be applicable to a large amount of endogenous target parts (as protein), comprise those (as amyloid-β (1-42) peptide or prostate specific antigen) that protein folding disease or cancer are relevant.In addition, the powerful antibody of immunogen epi-position was replied a little less than this method can create antagonism, thereby obtained the neutralizing antibody at allos target part, as the allos target from virus, antibacterial, fungus, PrPC or parasitic infection.
Should be understood that, the various embodiments of this paper use the non-natural immunogen (promptly, corresponding target part but contain the molecule of one or more alpha-non-natural amino acids) administration, when object is gone in inoculation, the immunogenic antibody of non-natural, B cell and/or T-cell will create antagonism, their cross reactions antagonism target part, as not comprising the disease association part of alpha-non-natural amino acid, and described target part is in subject or can be in subject.In other embodiment, can use the non-natural immunogen to produce antibody with the cross reaction of natural target part, described antibody is preventative then/and therapeutic gives object.
Therefore, in some embodiments of this paper, the method that the present invention comprises gives object by the non-natural immunogen that will comprise one or more alpha-non-natural amino acids, in object (as the disease association part, the autoinducer molecule of object, from the molecule of cause of disease in the subject, or from can be at the molecule of the intravital cause of disease of object etc.) produce immunne response at the target part.Object produce with at the corresponding antigenic antibody of target part that does not contain alpha-non-natural amino acid, described antibody cross reaction resists the particular target part.It should also be understood that the time, the antibody that is produced needn't have specificity for the epi-position of target part, the epi-position with alpha-non-natural amino acid on the corresponding non-natural immunogen of described epi-position.Method of the present invention can be used for breaking in the subject for target (as disease association) immunologic tolerance partly.In addition, when this paper carries out when describing by orthogonal translation system or other method of directly mixing (vide infra), also can modify (as chemical modification etc.) by other method in case create immunogenicity non-natural antigen.Usually this class indirect method with directly mix method such as orthogonal method coupling or as a supplement.
Such as in hereinafter describing in detail explanation, be used for comprising target part in the subject or can be usually in " non-natural " version of the intravital target part of object (as target part, from tumorigenic target part in the subject etc.) from the antibacterial that can infect object in the immunogen that object produces immunological response.In other words, the non-natural immunogen comprises the aminoacid sequence/structure identical with the target part arbitrarily, except target one or more aminoacid deformity partly are replaced by alpha-non-natural amino acid (the embodiment part that vide infra and show as in addition).In addition or in addition, the non-natural immunogen can comprise aminoacid sequence and one or more other alpha-non-natural amino acid residue of target part.In the specific embodiment, partly to compare with initial target, replacement and/or adding alpha-non-natural amino acid do not change (or only slightly changing) immunogenic conformational structure of non-natural.Therefore, three grades of non-natural immunogen and target part and/or quarternary structure can be identical, or closely similar each other.Placing one or more alpha-non-natural amino acids in the non-natural immunogen can select based on following arbitrarily, as comparing with the immunogen that target is partly originated, whether placement location can change immunogenic conformation, placement location whether make alpha-non-natural amino acid by antibody near (can combine with the zone of containing alpha-non-natural amino acid) etc. as antibody.Mixing the immunogenic alpha-non-natural amino acid of non-natural can be conservative or non-conservative replacement (comparing with natural amino acid corresponding in the target part).
Other embodiment of the present invention also comprises method preventative and/or the therapeutic treatment object, by giving one or more non-natural immunogens and/or resisting one or more and the immunogenic antibody of non-natural of corresponding natural target part cross reaction.
The present invention also comprises containing and is tested and appraised the embodiment that the target part of inferring at least for treatment responsive (as TNF α) (as the disease association part) produces the method for vaccine.Should be understood that this type of target part normally " natural ", and do not comprise any alpha-non-natural amino acid.Described method also comprises provides the non-natural immunogen, i.e. target part pairing " non-natural " version, and it comprises one or more alpha-non-natural amino acids, as replacing and/or add alpha-non-natural amino acid.Once more, described immunogen can comprise the structure conformation identical or close with the target part, therefore gives object non-natural immunogen and induces at immunogenic intersection antagonism target antibody partly.The present invention also comprises the vaccine that these class methods produce.
Should be understood that in the various embodiments of this paper, when creating immunological response and/or when giving prophylactic treatment etc., natural target partly can occur or not come across in the subject.Therefore, when describe this paper target part or when being positioned at subject, should be understood that to comprise that also wherein the target part can be positioned at subject.Therefore, target part can come from the esoteric tumor of object, or from the infectious agent that can infect object etc.
Therefore, as making an explanation in the whole text, in various embodiments, the target part can be the disease association part, born part, external source part etc.Target part itself can the immunogenic or part or weak immunogenic of right and wrong.External source target part can be from any organism (as antibacterial, virus etc.).Target part itself can be any autoantigen (as tumor relevant etc.).Mixing the immunogenic alpha-non-natural amino acid of non-natural can be any alpha-non-natural amino acid, vide infra, and can be positioned at any position of immunogen.Compare with the natural amino acid of target part, it can be conservative or non-conservative replacement that the alpha-non-natural amino acid in the immunogen plays.As hereinafter further describing, the non-natural immunogen also can be created (as orthogonal translation, solid phase synthesis etc.) by the multiple method of directly mixing.This paper typical embodiment is not created the non-natural immunogen by doping method indirectly, as post translational modification or chemical modification (but these class methods can be mixed the method coupling arbitrarily Yu directly, use as orthogonal translation or after directly mixing method such as orthogonal translation).

Embodiment
Provide following examples, with explanation but not requirement for restriction protection the present invention.Should be understood that embodiment as herein described and embodiment just in order to illustrate, it will be understood by a person skilled in the art that various modifications or the change made in view of the above, they are included in the scope of the application's design and scope and appended claims.
Embodiment 1: the alpha-non-natural amino acid with genetic coding is broken immunologic tolerance
Selective induction is replied at the strong immunization of oneself protein matter, or the immunogenicity that increases defined epitope in the exotic antigen has appreciable impact for the production of cancer, protein false folding and infectious disease vaccine.We have shown that the immunogenicity alpha-non-natural amino acid is mixed protein of interest matter produces the proteinic high titre antibody of cross reaction WT herein.Specifically, the single tyrosine residue (Tyr of Mus tumor necrosis factor-alpha (mTNF α) 86) sport right-Nitrobenzol alanine (pNO 2Phe) in mice, induce high titre antibody response, yet for Tyr 86→ Phe sudden change does not have remarkable antibody response.At pNO 2The antibody that Phe produces has the height cross reactivity to natural mTNF α, the death of and protection mice antagonism lipopolysaccharide (LPS)-cause.This method provides the antibody response of inducing at self and external defined epitope, and causes the neutrality immunne response.
A major challenge of vaccinology is to produce the effective ways selective induction to reply at the strong immunization of oneself protein matter now, or strengthens the immunogenicity of defined epitope in the exotic antigen, and described epi-position is induced and produced neutralizing antibody but the immunodominance of not having.Existing multiple this challenge of strategy reply, comprise exploitation improvement adjuvant, the auxiliary peptide of external source is introduced chimeric antigen, and use dna vaccination (Dalum etc. (1999), " at the inductive therapeutic antibodies of TNF alpha immunization " (Therapeutic antibodies elicited by immunization against TNF-alpha) Nat Biotechnol17:666-669; Makela etc. (2002), " evolution of coupling vaccine " (Evolution of conjugate vaccines) Expert Rev Vaccines1:399-410; Restifo etc. (1996), " novel vaccine: the virus that makes up inducing antitumor immunity " (The new vaccines:building viruses that elicit anti-tumor immunity) Curr Opin Immunol, 8:658-663; Baldridge etc., " vaccine adjuvant: immunology and clinical practice " (Vaccine Adjuvants:Immunological and Clinical Principles) C.J.Hackett, Harn, D.A., J compiles (Xiu Mana publishing house, New Jersey Tuo Tuowa) (Humana Press, Totowa, NJ, 2006), 235-255).What is interesting is, before nearly 50 years, Weigle (Weigle (1965) " autoimmune of inducing rabbit behind the homology Elityran of injection allos or change " (The induction of autoimmunity on rabbits following inj ections of heterologous or altered homologous thyroglobulin) J Exp Med121:289-308) show with the antibody that produces behind the rabbit Elityran immunize rabbit of the non-specific labelling of diazo compound derivative natural Elityran cross reaction.Although these experiments have produced high heterogenetic antigen, a kind of explanation is that chemical modification causes producing the epitope of inducing the high titre cross reacting antibody of generation.Similar, there is report T cell tolerance to be broken by autoreaction B cell, be easy to inducing T cell tolerance (Mamula etc. (1992) break the T cell tolerance with external and self common antigen: the research of cytochrome C autoimmune B and t cell epitope (Breaking T cell tolerance with foreign and self co-immunogens.A study of autoimmune B and T cell epitopes of cytochrome c) with having the different cross reaction exotic antigen of one or more aminoacid to carry out immunity with autoantigen J Immunol149:789-795).
Compare with the chemical method of the modifying protein of relative non-selectivity, may make protein produce highly accurate " chemical mutation " by the encode method of alpha-non-natural amino acid of hereditism now.Have above 50 kinds of alpha-non-natural amino acids and in antibacterial, yeast or mammalian cell, encode, comprise melts combine and post translational modification aminoacid, fluorescence and redox active amino acids, and photoreaction and chemical reaction aminoacid (Wang etc. (2001), " expanding colibacillary genetic coding " (Expanding the genetic code of Escherichia coli) Science 292:498-500; Chin etc. (2003), " the eucaryon genetic coding of expansion " (An expanded eukaryotic genetic code) Science 301:964-967; Xie and Schultz (2006) " protein chemistry workbox-expansion genetic coding " (A chemical toolkit for proteins-an expanded genetic code.) Nat Rev Mol Cell Biol 7:775-782).Specifically, the derivant with phenylalanine right-Nitrobenzol alanine (pNO 2Phe, Figure 1A) dope corresponding succinum nonsense codon in the bacterioprotein, have when the spectrum intervals probe high fidelity and good efficiency (Tsao etc. (2006), " in escherichia coli, the distance probes hereditism being mixed protein " (The genetic incorporation of a distance probe into proteins in Escherichia coli) J Am Chem Soc 128:.4572-4573)。Once used the nitro aryl (to compile " catalytic antibody " referring to Keinan in history as the high immunogenicity hapten Catalytic Antibodies (WV company, Wei En Haimu, 2005)), may be because the pi system of electron deficiency is tending towards Tyr and the Trp side chain interaction common with the antagonist binding site.Because its structural similarity, we comprise Phe → pNO at supposition 2Phe or Tyr → pNO 2The protein of Phe sudden change can produce the intensive immunne response with the native protein cross reaction.Therefore, we show with Mus tumor necrosis factor-alpha (mTNF α) Tyr 86→ pNO 2Phe muton immune mouse produces the high titre antibody to WT mTNF α response, therefore can effectively protect mice antagonism lipopolysaccharide (LPS) to stimulate.
Select the target protein of mTNF α as this research, because:(i) it is a cytokine through furtheing investigate, relate to the adjusting (Vassalli (1992), " pathophysiology of tumor necrosis factor " (The Pathophysiology of Tumor Necrosis Factors) Ann Rev Immunol 10:411-452) of infection, inflammation and autoimmune phenomena; (ii) this proteic biological property has carried out broad research, comprise its expression, structure, function and signal transduction mechanism (Vassalli (1992), " pathophysiology of tumor necrosis factor " (The Pathophysiology of Tumor Necrosis Factors) Ann Rev Immunol 10:411-452); Baeyens etc. (1999), " 1.4A differentiates mouse tumor necrosin down:to the adjusting of its selectivity and trimerizing " (The structure of mouse tumour-necrosis factor at 1.4 A resolution:towards modulation of its selectivity and trimerization.)

In this example, by genetic method with alpha-non-natural amino acid right-Nitrobenzol alanine (pNO 2Phe) introduce Mus tumor necrosis factor-alpha (mTNF α) to substitute residue Tyr 86Find with this pNO that contains 2The protein mice immunized of Phe can produce intensive neutralizing antibody and reply, and this replying can effective cross reaction take place with wild type mTNF α.And, find that this immunity can effectively protect the inductive death of mice antagonism lipopolysaccharide (LPS).The result shows the unique NO of the former part of the hyperimmunization that does not have in the protein that contains natural generation 2The oneself protein of group will be an exotic antigen by immune system recognition.Owing to comprise unique NO 2The structural similarity of group protein and native protein is at antibody and the corresponding oneself protein matter cross reaction that modifying protein caused.Therefore this method provides the conventional method of breaking oneself protein matter immunologic tolerance and producing vaccine.

Analyze pNO 2Phe 86The tertiary structure of mTNF α
In order to determine pNO 2The Phe sudden change is for pNO 2Phe 86MTNF α, Phe 86MTNF α, pNO 2Phe 42MTNF α, Phe 42MTNF α and pNO 2Phe 11The influence of three grades/quarternary structure of mTNF α is analyzed WT mTNF α and sudden change mTNF α sample (table 2) with fast protein liquid chromatogram.Figure 1B has shown the trimerical X-ray crystal structure of mTNF α (PDB ID code 2TNF) that contains Tyr-86, Asp42m and Lys-11 introducing thing.Use Superdex 75 10/300GL gels to infiltrate post (GE health care), go up at fast protein liquid chromatogram (FLPC) and analyze all proteins sample.In 25 ℃ of PBS buffer, carry out the size exclusion chromatograph with the flow velocity of 0.3ml/min.WT mTNF α and pNO 2Phe 86MTNF α concentration with>10mg/ml in 25 ℃ PBS buffer is dissolved fully.With Bole's (Bole's laboratory, Ai Kulaisi, the California, the U.S.) (Bio-Rad Labs, Hercules, CA, gel USA) infiltrate the molecular weight standard product pillar are calibrated, and standard substance comprise the B-12 (1.35kDa) of Elityran (670kDa), gamma Globulin (158kDa), ovalbumin (44.0kDa), Myoglobin (17.0kDa) and vitamin.Measure the light absorption of elution fraction behind the protein eluting at 280nm.
WT mTNF α and pNO 2Phe 86MTNF α all shows similar retention time, and corresponding molecular weight and its trimeric form are complementary.The logarithm that Fig. 4 has shown protein standard substance molecular weight is mapped in the retention time that Superdex 75 10/300GL gels infiltrate on the post relatively.Ignore Elityran (670kDa) in the calculating, because its molecular weight far surpasses the separating ranges of Superdex 75 10/300GL posts (3kDa-70kDa).Figure based on Fig. 4 determines pNO 2Phe 86MTNF α, WT mTNF α, mTNF α F 86, pNO 2Phe 42MTNF α, mTNF α F 42And pNO 2Phe 11The molecular weight of mTNF α tetramer structure, (as follows) as shown in table 2.Monomer pNO 2Phe 86MTNF α eluting retention time is 41.47 minutes.
The observed value and the value of calculation of table 2:WT mTNF α and mTNF α muton molecular weight
Logarithm to protein standard substance molecular weight is mapped in the retention time that Superdex 75 10/300GL gels infiltrate on the post relatively, determines pNO by this figure 2Phe 86TNF α, Phe 86MTNF α, pNO 2Phe 42MTNF α, Phe 42MTNF α, pNO 2Phe 11MTNF α and the tetrameric molecular weight of WT mTNF α.
PNO 2Phe 86The analysis of mTNF α biologic activity
In NF κ B-luciferase reporting cell line, proteinic biologic activity is detected by the activation of measuring mTNF α-inductive NF κ B.Use HEK293 cell (Ye etc., (2000) " ER pressure inducement SREBP processive enzyme cutting film is in conjunction with ATF6 " (ER Stress Induces Cleavage of Membrane-Bound ATF6 by the Same Proteases that Process SREBPs) of stably express NF κ B-Luc in the reporter gene experiment Mol Cell6:1355-1364).The nitrated stabilized cell of trypsin is resuspended among the DMEM that contains 10%FBS, and concentration is 5x10 5Cells/ml, with 20 μ l/ holes plant in the blank of 384-hole (Ge Leina company, Lang Wude, Florida State) (Greiner, Longwood, FL).Contain 5%CO at 37 ℃ 2Incubator for tissue culture in hatch 2 hours after, in cell, add 20 μ l TNF α.Continued incubated cell 24 hours.(Promega, Madison WI) measure uciferase activity, and read plate with the cold light plate reading machine to add 20 μ l Bright-Glo (Pu Luomaige company, state of Wisconsin Madison).Experimental result shows that WT mTNF α activates NF κ B signal transduction in the NF κ B-luciferase reporting cell line.By contrast, pNO 2Phe 86Muton (Fig. 5) only has the activity of WT mTNF α in 2% experiment, this with before about Tyr 86By receptors bind necessary, introduce 86 residue sudden changes and cause the active significantly report unanimity of forfeiture (Van Ostade etc. (1994), " the structure-activity research of human tumour necrosis factor " (Structure-activity studies of human tumour necrosis factors) Protein Engineering7:5-22; Loetscher etc. (1993), " huamn tumor necrosis factory alpha (TNF α) muton has exclusive specificity for 55-kDa or 75-kDa TNF receptor " (Human tumor necrosis factor alpha (TNF alpha) mutants with exclusive specificity for the 55-kDa or 75-kDa TNF receptors) J Biol Chem268:26350-7; Zhang etc. (1992), " the rite-directed mutagenesis analysis and the structure-function relationship of human tumor necrosis factor-alpha receptor binding site " (Site-directed mutational analysis of human tumor necrosis factor-alpha receptor binding site and structure-functional relationship) J Biol Chem267:24069-75).In the MALDI-TOF spectrum, find another one peak and pNO 2Phe 86Preceding two the amino acid whose deletions of mTNF α are corresponding, and (table 1, Fig. 2), supposition is because due to excessively digesting in the Xa proteolysis cutting step.Preceding two amino acid whose deletions of N-terminal are minimal effect TNF activity only, therefore be difficult to truncated protein matter is separated (Van Ostade etc. (1994), " the structure-activity research of human tumour necrosis factor " (Strncture-activity studies of human tumour necrosis factors) from full length protein Protein Engineering7:5-22), so, comprise sudden change mTNF α and WT contrast with mixture direct immunization mice.
Experiment in addition shows the terminal His of N- 6Whether label exists does not influence immune result (Figure 13).Five Bcl2 mices as #3262, #3263, #3264, #3331, #3351, are divided into two groups at random, use His respectively 6-Phe 86MTNF α (WT) or His 6-pNO 2Phe 86MTNF α injects, and used scheme is RIMMS (multidigit point repeats an immunity) scheme (as mentioned below).Simply say 18 days mice is carried out 8 injections.In the per injection, contain the proteinic 200 μ l PBS of 5 μ g and complete Freund's adjuvant (CFA) and mix at 1: 1, or be mixed near the injection of specific site remaining 6 periphery lymph nodes at 1: 1 with incomplete Freund's adjuvant (IFA) as injection first.In the time of the 21st day,, use the goat anti-mouse IgG second antibody of horseradish peroxidase, determine at pNO by enzyme-linked immunosorbent assay (ELISA) 2Phe 86MTNF α and Phe 86The antibody titer of mTNF α.Referring to Figure 13.1K post) or 10,000 times (1: carry out ELISA 10K post) among this figure, with 100 times (1: 100 pre) of mice serum dilution before the immunity, with 1,000 times of mice serum dilution after the immunity (1:.With WT mTNF α (WT, first three root post) or pNO 2Phe 86MTNF α (mod, back three posts) The wraps by elisa plate.
PNO 2Phe 86Anti-pNO in the mTNF alpha immunization mice 2Phe 86The serum titer analysis of mTNF α or WT mTNF α
MTNF α can be survived and do not shown the unusual (Pasparakis etc. (1996) of obvious phenotype, " immunity and inflammatory response in the TNF α deficient mice: tumor necrosis factor is at former generation B cell folliculus, the formation of dendritic cells,follicular network and germinal center, and the pivotal role in the sophisticated humoral immunization " (Immune and inflammatory responses in TNF alpha-deficient mice:a critical requirement for TNF alpha in the formation of primary B cell follicles, follicular dendritic cell networks and germinal centers, and in the maturation of the humoral immune response) J Exp Med 184:1397-1411), show that mice can survive at TNF α He in the immunne response, produce and biologic activity thereby make immunized mice can be used for analyzing the TNF Alpha antibodies.In order to measure pNO 2Phe 86The immunogenicity of mTNF α muton, 32 C57BL/6 mices are divided into three groups and also inject pNO respectively 2Phe 86MTNF α, WT mTNF α and PBS buffer, used scheme is RIMMS (multidigit point repeats immunity) scheme (Kilpatrick etc. (1997), " using the RIMMS affine sophisticated monoclonal antibody of exploitation fast " (Rapid development of affinity matured monoclonal antibodies using RIMMS) Hybridoma16:381-389).For fear of the caused side effect of mTNF α toxicity, use per injection 5 μ g mTNF α (Libert etc., (1999) " identifying the locus that No. 12 end of chromosome control of mice tumor necrosis factor induces the lethal shock to tolerate " (Identification of a locus on distal mouse chromosome 12 that controls resistance to tumor necrosis factor-induced lethal shock) in the research always Genomics55:284-289).Fig. 6 shows with PBS (6A), WT mTNF α (6B), pNO 2Phe 86MTNF α (6C) or Phe 86Serum titer in the immune C57BL/6 mice of mTNF α (6D).Simply say 17 days mice is carried out 8 injections.In the per injection, contain the proteinic 200 μ l PBS of 5 μ g and complete Freund's adjuvant (CFA) and mix at 1: 1, or be mixed near the injection of specific site remaining 6 periphery lymph nodes at 1: 1 with incomplete Freund's adjuvant (IFA) as injection first.In the time of the 21st day,, use the goat anti-mouse IgG second antibody of horseradish peroxidase, determine at pNO by enzyme-linked immunosorbent assay (ELISA) 2Phe 86The antibody titer of mTNF α and WT mTNF α.
In order to carry out ELISA, (Nunc, Rochester's high absorption 384-orifice plate (Lang Ke company, New Jersey Rochester) NY) are spent the night with 4 ℃ of bags of 30 μ l, 0.5 μ g/ml protein.(PBST) washes plate twice with the PBS+0.05% polysorbas20, also washes with PBST once more with the PBS sealing that contains 80 μ l 1%BSA.Successively with plate and 20 μ l first antibodies or with the serum of the PBS dilution that contains 1%BSA, the link coupled goat anti-mouse IgG of 20 μ l HRP-(Jackson's immune Research laboratory, Xi Geluowei, Pennsylvania) (Jackson ImmunoResearch Laboratories, West Grove, PA) and 20 μ l tmb substrate (KPL, the Gaithersburg, the Maryland State) (KPL, Gaithersburg, MD) hatch, and measure the 650nm absorption.Wash plate with PBST between hatching.
Measure anti-WT mTNF α (Fig. 6 A and 6B, left side post) or pNO with ELISA 2Phe 86MTNF α (Fig. 6 A and 6B, right side post).For Phe 86MTNF alpha immunization mice is measured anti-WT mTNF α (Fig. 6 C and 6D, left side post) or Phe with ELISA 86MTNF α (Fig. 6 C and 6D, right side post).Before the measurement, with the PBS buffer dilute serum sample that contains 1%BSA.With WT mTNF α or anti-pNO in the PBS buffer mice immunized serum is only arranged 2Phe 86MTNF α and WT mTNF α IgG titre be remarkable (Fig. 6) not.As expection, WT mTNF α should be tolerated by the mouse immune system as oneself protein matter.By contrast, use pNO 2Phe 86The mice of mTNF alpha immunization has shown pNO 2Phe 86The obvious high serum titer of mTNF α (Fig. 6 C, the right side post of every pair of pillar) and WT mTNF α (Fig. 6 C, the left side post of every pair of pillar).Therefore, single pNO 2Intensive immunne response has been induced in Phe sudden change (making the monomer molecule amount change 29 dalton), obtains the antibody with the cross reaction of WT mTNF α height.Use the Bcl-2 mice to obtain analog result, show that this result does not rely on strain (Fig. 7).The RIMMS scheme that reuses comprises 17 days carries out 8 injections (per injection 5g), carries out initial injection under the condition that CFA exists, and IFA remains 7 injections under existing.Measure anti-WT mTNF α (first, second roots of four pillars of each group) or pNO with ELISA 2Phe 86MTNF α (second, third root pillars of four pillars of each group).Before the measurement, with the PBS buffer 1/100 or the 1/1000 dilute serum sample that contain 1%BSA.
We have also detected the immunogenicity when not having immunostimulant, find to use pNO 2Phe 86MTNF alpha immunization mice has also been induced significant anti-TNF alpha titre (Fig. 8) when existing without any adjuvant, show that this scheme not needing can be used for the treatment condition of strong adjuvant.Under the condition that does not have CDA or IFA, with (a) WT mTNF α, or (b) pNO 2Phe 86The mTNF alpha immunization carried out the serum titer of the Bcl-2 mice of 8 injections (per injection 5 μ g protein) in 17 days.Measure anti-WT mTNF α (the left side post of every coupled columns) or pNO with ELISA 2Phe 86MTNF α (the right side post of every coupled columns).Before the measurement, with the PBS buffer dilute serum sample that contains 1%BSA.
And, order pNO 2Phe 86MTNF α carries out 8 immunity back antibody responses and continues, after 19 weeks very strong (Figure 14).Clinical application especially needs this long-term persistence, because the therapy defective is that after immunity stops the autoantibody titre reduces rapidly at present.Figure 14 has shown the result who measures the serum titer persistence.In order to carry out this experiment, use pNO 2Phe 86Three Bcl-2 transgenic mices of mTNF alpha immunization.After order is carried out 8 immunity, get blood at the appointed time and carry out anti-pNO 2Phe 86The elisa assay of mTNF α.Before each the measurement, with 1: the 100 dilute serum sample of PBS buffer that contains 1%BSA.The corresponding last immunity of T and get time span between the blood.
In order to verify that immunne response is the result of immunogenicity nitro aryl in the alpha-non-natural amino acid, produce Tyr 86→ Phe sudden change mTNF α (Phe 86MTNF α).After confirming the trimer quarternary structure with the size exclusion chromatograph, CFA/IFA exist or non-existent condition under with the immune Bcl2 mice of this muton.For mice immunized under the no adjuvant condition, the RIMMS scheme comprises 17 days 8 times injections (per injection 5g protein).To with the adjuvant existence condition under mice immunized, CFA as first the injection, IFA is used to remain 7 injections.Measure anti-WT mTNF α (Fig. 9, first, second root of four pillars of each group) or Phe with ELISA 86MTNF α (Fig. 9, second, third root pillar of four pillars of each group).Before the measurement, with the PBS buffer 1/100 or the 1/1000 dilute serum sample that contain 1%BSA.Exist or do not exist under the condition of adjuvant all not produce significant anti-TNF alpha titre, show NO 2Be to break immunologic tolerance needed (Fig. 6 D and 9).And, pNO 2Phe 86MTNF alpha specific CD 4 +The T cell only produces with this mutein immune mouse the time, and is using WT mTNF α or Phe 86Then do not produce during mTNF alpha immunization mice (Figure 15 A).By contrast, when stimulating from pNO at external use WT mTNF α 2Phe 86The CD of mTNF alpha immunization mice 4 +During the T cell, do not observe significant propagation (Figure 15 B).In order to carry out the T-cell proliferation experiment, the magnetic consumption by using MACS pearl (beautiful day Ni biotech company) (Miltenyi Biotec) separates CD4 from immune mouse from lymph node +The T cell.Then the T cell being placed the antigen that increases progressively with radiating splenocyte and quantity from natural B cl-2 mice cultivates.Culture is hatched 48h, use then [ 3H] the thymidine pulse labeling spends the night.Collect culture plate and place on the filter paper pads, and ((PerkinElmer) carries out quantitatively with TopCount scintillation counter (Perkinelmer Inc.).
Use the preliminary epitope mapping experiment of mTNF α muton and WT mTNF α fragments of peptides to show for pNO 2Phe 86The polyclone of mTNF α is replied and is related to a plurality of protein epitopes.To sum up, these results show pNO 2Phe mixes mTNF α sequence and has created t cell epitope, has strengthened the help of T cell for the effective immunne response that triggers antagonism disease relative protein white matter.Other immunization protocol (as, with sudden change and WT TNF α sequential immunization) also can produce the cross reacting antibody of high titre.(1999) such as these results and Dalum, " therapeutic antibodies that antagonism TNF alpha immunization obtains " (Therapeutic antibodies elicited by immunization against TNF-alpha) Nat Biotechnol 17:666-669 is consistent, and this piece article mixes mTNF α to break immunologic tolerance with immunodominance t helper cell epi-position.Yet present scheme causes existing in the protein little disturbance, can not destroy its three grades folding or its expression of appreciable impact, solubility or stability.
Computer analysis prediction Tyr to potential MHC II class DR epi-position among the TNF α based on sequence 86Peptide sequence on every side is not T-cell epitope (Steed etc. (2003), " the negative TNF variant of appropriate design dominance makes TNF signal transduction inactivation " (Inactivation of TNF Signaling by Rationally Designed Dominant-Negative TNF Variants) Science 301:1895-1898).In order to begin to inquire into the universality of this method, we have detected and have carried out pNO in other site 2Phe replaces whether have similar effect.The surperficial exposed residue Asp of trimerizing or receptors bind will do not participated in 42Sport pNO 2Phe.After SDS-PAGE and mass spectrum affirmation sudden change, use pNO 2Phe 42MTNF α or Phe 42MTNF α muton immunity two groups of C57BL/6 mices (Figure 10).The RIMMS scheme is included in adjuvant and does not have following 17 days and carry out 8 injections (per injection 5g protein).ELISA measures anti-WT mTNF α (Figure 10 A, first of every group of three pillars; Figure 10 B, first of every pair of pillar), anti-pNO 2Phe 42MTNF α/pNO 2Phe 11MTNF α (Figure 10 A, Figure 10 A, second of every group of three pillars; Figure 10 B, in 7,8,9 second of every pair of pillar), or anti-Phe 42MTNF α (Figure 10 A, every group of pillar the 3rd) or PBS (Figure 10 B, in 5,6 second of every pair of pillar).Before the measurement, with PBS buffer 1/100 (Figure 10 A) or 1/800 (Figure 10 B) dilute serum sample of containing 1%BSA.Only work as pNO 2Phe 42MTNF α induces significant anti-TNF alpha titre when carrying out immunity, use pNO 2Phe 42The mice of mTNF alpha immunization is induced significant anti-TNF alpha titre.This result shows pNO 2Phe mutation is a quite general method of giving specific self or exotic antigen hyperimmunity.
With another surperficial exposed residue Lys 11Sport pNO 2Phe obtains analog result.These results show pNO 2The method that one of Phe mutation is quite general gives specific self or exotic antigen hyperimmunity can be not limited only to the replacement that the surface exposes Tyr or Phe residue.Yet preliminary study shows at 104 and 19 mixes pNO 2The Phe effect relatively a little less than.Use pNO 2Phe 104MTNF alpha immunization C57BL/6 mice produces the antibody that lacks with the remarkable cross reaction of natural mTNF α.Therefore, environmental effect has influence for the characteristics of determining immunne response.At last, possible genetic coding immunogenicity aminoacid also has same favourable application, perhaps for littler antigen, and can be by the synthetic immunogenicity alpha-non-natural amino acid that mixes of semi-synthetic or full peptide.
Analyze pNO 2Phe 86MTNF alpha immunization mice is to replying that LPS stimulates
Next we measure in serious endotoxemia mouse model and use pNO 2Phe 86Can TNF alpha immunization inoculation mice make its antagonism lipopolysaccharide (LPS) stimulate (F.Niessen etc. (2008) " dendritic cell PAR-S1P3 signal transduction links together blood coagulation and inflammation " (Dendritic cell PAR-S1P3 signalling couples coagulation and inflammation) Nature 452:654-658.In this model, the inductive septic shock of known LPS participates in generation and the release of TNF α.The experiment of all research mice endotoxemias is all carried out according to NIH's animal protection guide (National Institutes of Health Animal Protection Guidelines), and through Si Kelipu academy's animal care and the approval of use committee.By vortex 30 seconds with lipopolysaccharide (LPS, escherichia coli (E.coli) O111:B4, CEB company (Calbiochem/EMD Biosciences), Santiago, California, the U.S.) be dissolved in 37 ℃ of normal saline (0.9%w/v NaCl), respectively carry out 2 minutes supersound process before and afterwards.Under 2% isoflurane anesthesia, male C57BL/6 mice ((maine state of u.s.a Ba Er Haber (the Bar Harbor of Jackson Lab to 9 ages in week, ME, USA)) peritoneal injection 7.5mg/kg LPS is to carry out passive immunity, and perhaps the injected in mice 8.5mg/kg LPS to 15 ages in week carries out active immunity.All experiments are all in that day alternates with night in 12 hours is indoor, carry out under the steady-state conditions (temperature 20-22 ℃ with relative humidity 40-60%).Accept the Kaplan-Meier survival curve of the mice of active or passive immunity and see Figure 11.Make the Kaplan-Meier curve, and analyze survival difference with the logarithm rank tests.
With PBS, WT mTNF α and pNO 2Phe 86MTNF alpha immunization C57BL/6 mice.After finishing above-mentioned immunization protocol,, determine their survival rate to injecting LPS (8.5mg/kg) in these mouse peritoneums.In Figure 11 A, will utilize pNO 2Phe 86The mice of mTNF α or WT mTNF alpha immunization (8 every group) is made comparisons with 7 mices accepting false immunity.Demonstration is compared with wild type and is used pNO 2Phe 86The survival advantage of the mice of mTNF alpha immunization (p<0.01).In Figure 11 B, will utilize 100 μ g from pNO 2Phe 86The mice (8 every group) of the IgG purification injection of mTNF α or wild type immune mouse is made comparisons with the contrast of accepting saline injection.Demonstration is compared with wild type and is used pNO 2Phe 86The survival advantage of the mice of mTNF alpha immunization (p<0.01).In Figure 11 C, mice (6 every group) is accepted 100 μ L from pNO 2Phe 86MTNF α or wild type mTNF alpha immunization mice compile serum.Demonstration is compared with wild type and is used pNO 2Phe 86The survival advantage of the mice of mTNF alpha immunization (p<0.01).Control mice is injected isopyknic normal saline.
Shown in Figure 11 A, use pNO 2Phe 86The survival advantage (87.5%) of mTNF alpha-mutant mice immunized is apparently higher than the mice (survival rate 12.5%) of accepting PBS and WT mTNF alpha immunization.Similarly, accept to hang oneself pNO 2Phe 86The survival rate (83.3-87.5%) of the C57BL/6 mice that compiles serum (100uL) or IgG purification antibody (4mg/kg) of the Bcl-2 mice of the pre-immunity of mTNF α apparently higher than the mice that compiles serum or IgG (16.7-25.0%) of the Bcl-2 mice of the WTmTNF alpha immunization of accepting to hang oneself (Figure 11 B, 11C).Therefore, these results show, the single NO of oneself protein matter 2The Phe mutation induction is replied at the intensive cross reacting antibody of native protein, thereby produces protective effect in disease model.At present, we expand to other TNF α dependency models with these researchs, comprise collagen-induced arthritis (CIA) model and KRN transgenic mice (K/BxN) model (Ditzel (2004) " K/BxN mice: people's inflammatory arthritis model " (arthritis (CIA) model and KRN transgenic mouse (K/BxN) model (Ditzel (2004) " The K/BxN mouse:A model of human inflammatory arthritis) Trends Mol Med 10:40-45).
IgG antibody used in the above-mentioned injection is by being loaded into Mus serum 10ml agarose coupling protein G affinity column (γ combination+agarose (GammaBind Plus Sepharose), Pharmacia biotech company (Pharmacia Biotech), the New Jersey Piscataway is prepared on USA).PBS (pH 7=4) with three times of column volumes washs this post.0.1M acetic acid (pH 3=0) with the twice column volume carries out eluting.Use among the 1M Tris/HCl (pH=9.0) then and eluent, and dialyse with PBS (pH=7.4).
Stimulated preceding 24 hours at endotoxin, mice is carried out passive immunity.In first experiment, mice is accepted peritoneal injection 100 μ L from pNO 2Phe 86MTNF α or WT mTNF alpha immunization mice compile serum.Second winding is subjected to 4mg/kg by pNO 2Phe 86The IgG of the mice serum purification of mTNF α or WT mTNF alpha immunization.Control mice is injected isopyknic normal saline.
Above-mentioned discovery shows, in TNF α dependent form mouse model, and Tyr 86To pNO 2(with the proteinic unique difference of WT-is to contact site usefulness-NO at solvent in the single sudden change of Phe 2Group replace to replace-and OH) significantly strengthen proteinic immunogenicity and caused neutralizing antibody to be replied.With residue 86 with close on residue 85 mutation and become Ala pNO 2Phe 86Or the influence of WT protein antibody titre is very little, shows the discontinuous epi-position of these antibody recognition.The result shows the unique NO of the former part of the hyperimmunization that does not have in the protein that contains natural generation 2The protein of group will be exotic antigen by immune system recognition.Because structure is closely similar, the antibody capable of initiation and corresponding oneself protein matter generation cross reaction, thus break immunologic tolerance.
This embodiment shows and may pass through pNO 2The Phe fixed point is mixed protein epitope, breaks immune self tolerance as the epi-position of target oneself protein matter, for example is used to produce vaccine.Though but the protein inducing self-body antibody of known change, the disease of giving the immunogenic change of protein limits characteristic makes their generation use the complicated (Lerner etc. (1968) " inducing acute glomerulonephritis with the soluble antigen that separates from normal homology and self urine in rabbit " (The induction of acute glomerulonephritis in rabbits with soluble antigens isolated from normal homologous and autologous urine) that become with treatment J Immunol100:1277-1287). for example, used Ah 's acyl-sulphonyl in the research of Weigle-thyroglobulin prepared product comprises per molecule thyroglobulin~50 azo and connects (Weigle (1965) " do not contain adjuvant and inject unaltered thyroid gland immunoglobulin (Ig) generation thyroiditis and antibody in the rabbit that stimulates with the thyroid gland immunoglobulin (Ig) that changes in advance " (The production of thyroiditis and antibody following injection of unaltered thyroglobulin without adjuvant into rabbits previously stimulated with altered thyroglobulin)J Exp Med122:1049-1062), the antigen that obtains the height heterologous and may assemble or partly fold.Similar, insert the T-cell epitope in antigenic different loci and can create with native protein and compare tertiary structure, solubility and stable immovable protein.By contrast, the change of this paper has clear and definite chemistry definition and is confined to single residue.As and if these sudden changes do not influence proteic overall quarternary structure and solubility thereof.Therefore the antibody that obtains more may discern the corresponding epi-position in the native protein.At last, contain pNO 2The TNF alpha-mutant of Phe is induced the cross reaction immunne response of protectiveness, and need not strong adjuvant, and resulting high titre was kept 4 months.These characteristics help the treatment of the our science of law and use.
This scheme can be applicable to other oneself protein matter, comprises that those (as starch β 1-42 peptide) or cancers with the protein folding disease association are relevant.In addition, by introducing pNO in weak immunogenicity or reticent epi-position 2Phe group, this method can produce the strong antibody response at the cause of disease zone, predict that it obtains antagonism virus.The neutralizing antibody of antibacterial or parasitic infection (as, the CS1 protein of malaria or the E410 epi-position of HIV-1 gp41).And, immunogenicity aminoacid selectivity is mixed protein help producing functional antibodies, as g protein coupled receptor, and other is difficult to produce the agonist or the antagonist of the membrane-bound receptor of strong antibody response in history.The architecture basics of current this phenomenon and to it among discussion that human diseases is used is being illustrated.

Experimental program comprises 17 days carries out 8 injections (per injection 5 μ g protein), and initial being injected under the condition that has complete Freund's adjuvant (CFA) carried out, and remaining being injected under the condition that has incomplete Freund's adjuvant (IFA) carried out.Measure anti-WT mTNF α (the left side post of the every coupled columns of 1-32) or pNO with ELISA 2Phe 86MTNF α (the right side post of the every coupled columns of 1-32).For Phe 86MTNF alpha immunization mice (Fig. 6 D), ELISA measures antagonism WT mTNF α (the left side post of the every coupled columns of 33-36) or Phe 86MTNF α (the right side post of the every coupled columns of 33-36).Before the measurement, with 1: the 1000 dilute serum sample of PBS buffer that contains 1%BSA.
Use the Bcl-2 mice to obtain and last analog result, show that this result does not rely on strain (Fig. 7).Fig. 7 has shown WT mTNF α or pNO 2Phe 86Antagonism WT mTNF α and pNO in the mTNF alpha immunization Bcl2 mice 2Phe 86The serum titer level of mTNF α.The RIMMS scheme comprises 17 days carries out 8 injections (per injection 5 μ g protein), and initial being injected under the condition that has CFA carried out, and remaining being injected under the condition that has IFA carried out.Measure anti-WT mTNF α (first, second roots of four pillars of each group) or pNO with ELISA 2Phe 86MTNF α (second, third root pillars of four pillars of each group).Before the measurement, with the PBS buffer 1: 100 or 1: 1 that contains 1%BSA, 000 dilute serum sample.
Fig. 8 has shown pNO under the condition that does not have adjuvant to exist 2Phe 86MTNF alpha immunization mice serum titre measurement result.This immune induction significant anti-TNF alpha titre, show that this scheme do not need under the treatment condition of strong adjuvant can be applied to.。Fig. 8 A has shown the serum titer of WT mTNF alpha immunization Bcl-2 mice, and Fig. 8 B has shown pNO 2Phe 86The titre of mTNF alpha immunization mice.Followingly carry out immunity: under the condition that does not have CFA or IFA to exist, carried out 8 injections (per injection 5 μ g protein) in 17 days.Measure anti-WT mTNF α (the left side post of every coupled columns) or pNO with ELISA 2Phe 86MTNF α (the right side post of every coupled columns).Before the measurement, with 1: the 1000 dilute serum sample of PBS buffer that contains 1%BSA.
In order to verify that immunne response is the result of immunogenicity nitro aryl in the alpha-non-natural amino acid, produce Tyr 86→ Phe muton mTNF α (Phe 86MTNF α) and exist or lack under the condition of CFA/IFA with this muton Bcl2 mice.Fig. 9 provides under the condition that has or not adjuvant to exist and has used Phe 86Anti-wt mTNF α and the Phe of mTNF alpha immunization Bcl2 mice 86MTNF α serum titer is measured.Exist or do not exist under the condition of adjuvant all not produce significant anti-TNF alpha titre, show NO 2Be that to break immunologic tolerance needed.
For mice immunized under the no adjuvant condition, the RIMMS scheme comprises 17 days 8 times injections (per injection 5 μ g protein).To with the adjuvant existence condition under mice immunized, CFA as first the injection, IFA is used to remain 7 injections.Measure anti-WT mTNF α (first, second roots of four pillars of each group) or Phe with ELISA 86MTNF α (second, third root pillars of four pillars of each group).Before the measurement, with the PBS buffer 1: 100 or 1: 1 that contains 1%BSA, 000 dilute serum sample.
Figure 10 shows that the immunogenicity of determining other surface site of TNF α determines result of experiment; Figure 10 A has shown and has used pNO 2Phe 42MTNF α or Phe 42MTNF alpha immunization C57BL/6 mouse anti WT mTNF α, pNO 2Phe 42MTNF α and Phe 42The serum titer of mTNF α.Shown among Figure 10 B and used pNO 2Phe 11MTNF α or WT mTNF alpha immunization C57BL/6 mouse anti WT mTNF α, PBS and pNO 2Phe 11The serum titer of mTNF α.Only work as pNO 2Phe 42MTNF α induces significant anti-TNF alpha titre when carrying out immunity, use pNO 2Phe 42The mice of mTNF alpha immunization is induced significant anti-TNF alpha titre.This result shows pNO 2Phe mutation is a quite general method of hatching specific self or exotic antigen hyperimmunity.
The RIMMS scheme is included in does not have adjuvant to carry out 8 injections (per injection 5 μ g protein) in following 17 days.ELISA measures anti-WT mTNF α (Figure 10 A, first of every group of three pillars; Figure 10 B, first of every pair of pillar), anti-pNO 2Phe 42MTNF α/pNO 2Phe 11MTNF α (Figure 10 A, Figure 10 A, second of every group of three pillars; Figure 10 B, in 7,8,9 second of every pair of pillar), or anti-Phe 42MTNF α (Figure 10 A, every group of pillar the 3rd) or PBS (Figure 10 A, in 5,6 second of every pair of pillar).Before the measurement, with PBS buffer 1/100 (Figure 10 A) or 1/800 (Figure 10 B) dilute serum sample of containing 1%BSA.
In this model, the inductive septic shock of known LPS participates in generation and the release of TNF α.Next we measure in serious endotoxemia mouse model and use pNO 2Phe 86Can TNF alpha immunization inoculation mice make its antagonism lipopolysaccharide (LPS) stimulate (F.Niessen etc. (2008) " dendritic cell PAR-S1P3 signal transduction links together blood coagulation and inflammation " (Dendritic cell PAR-S1P3 signalling couples coagulation and inflammation) Nature 452:654-658.Can Figure 11 has shown in serious endotoxemia model improve the experimental result of mouse existence with the pNO2Phe86mTNF alpha immunization.Shown and accepted initiatively or the Kaplan-Meier survival curve of the mice of passive immunity.In Figure 11 A, will utilize pNO 2Phe 86The mice of mTNF α or WT mTNF alpha immunization (8 every group) is made comparisons with 7 mices accepting false immunity.Demonstration is compared with WT and is used pNO 2Phe 86The survival advantage of the mice of mTNF alpha immunization (p<0.01).In Figure 11 B, will utilize 100 μ g from pNO 2Phe 86The mice (8 every group) of the IgG purification injection of mTNF α or WT immune mouse is made comparisons with the contrast of accepting saline injection.Demonstration is compared with WT and is used pNO 2Phe 86The survival advantage of the mice of mTNF alpha immunization (p<0.01).In Figure 11 C, mice (6 every group) is accepted 100 μ L from pNO 2Phe 86MTNF α or WT mTNF alpha immunization mice compile serum.Compare with WT and to use pNO 2Phe 86The survival advantage of the mice of mTNF alpha immunization (p<0.01).Shown WT.
Figure 12 provides and has been derived from pNO 2Phe 86The MS/MS of the 8 polyprotein enzymatic fragments of mTNF α analyzes.Contain pNO with single-letter for buying expression 2Phe proteolysis fragments sequence (X=pNO 2Phe).The ion fragment that has shown observed y and b series.Proof pNO 2Crucial y and b ion that Phe mixes are b 5, b 6, b 7, y 7, y 6, y 5And y 4All quality are reported with single isotopic mass.MS/MS analyzes with 86 residues and mixes pNO 2The pattern of Phe is accurately mated.
Figure 13 has shown His 6-Phe 86MTNF α (WT) or His 6-pNO 2Phe 86The terminal His of the N-of mTNF α 6Label does not have influence for the follow-up immunization experimental result.
Clinical application especially needs the long-term persistence of serum antibody, because the therapy defective is that after immunity stops the autoantibody titre reduces rapidly at present.Figure 14 has shown the experimental result of definite anti-TNF alpha immunne response serum titer persistence.Use pNO 2Phe 86Three Bcl-2 transgenic mices of mTNF alpha immunization.After order is carried out 8 immunity, get blood at the appointed time and carry out anti-pNO 2Phe 86The elisa assay of mTNF α.Before each the measurement, with 1: the 100 dilute serum sample of PBS buffer that contains 1%BSA.The corresponding last immunity of T and get time span between the blood.First of every group of 6 posts is before getting blood, and second is t=1 week, and the 3rd is t=8 week, and the 4th is t=12 week, and the 5th is t=16 week, and the six roots of sensation is t=19 week.
Figure 15 has shown T cell proliferation experiment result.Figure 15 A has shown use by oneself WT mTNF α, pNO 2Phe 86MTNF α and Phe 86The CD4 of the Bcl-2 transgenic mice of mTNF alpha immunization +The T cell is at the pNO of external use gradient dilution 2Phe 86MTNF α stimulates.Figure 15 B has shown use by oneself WT mTNF α, pNO 2Phe 86MTNF α and Phe 86The CD4 of the Bcl-2 transgenic mice of mTNF alpha immunization +The T cell stimulates at the WT of external use gradient dilution mTNF α.PNO 2Phe 86MTNF alpha specific CD 4 +The T cell only produces with this mutein immune mouse the time, and is using WT mTNF α or Phe 86Then do not produce during mTNF alpha immunization mice.By contrast, when stimulating from pNO at external use WT mTNF α 2Phe 86The CD of mTNF alpha immunization mice 4 +During the T cell, do not observe significant propagation.
Embodiment 2: the Mechanism Study that stops tolerance with the alpha-non-natural amino acid immunochemistry
The characteristic and the persistency of the polyclone IgG antibody that is produced that 2 couples of embodiment have mixed the TNF α of alpha-non-natural amino acid characterizes, for alpha-non-natural amino acid is induced (as pNO 2Phe-induces) the generality of forfeiture of self tolerance increased new support.Embodiment 2 has shown that a plurality of surface residue independent mutations with Mus tumor necrosis factor-alpha (mTNF α) are right-Nitrobenzol alanine (pNO 2Phe) caused the polyclone of T cell-dependence and continue anti--mTNF α IgG autoantibody and reply and continued at least 40 weeks.Embodiment shows antibodies a plurality of epi-positions on mTNF α, and the protection mice exempts from the inductive serious endotoxemia of lipopolysaccharide (LPS) stimulation.With Mus retinol binding protein matter (RBP4) pNO 2Phe 43The muton immune mouse also shows the IgG antibody response that can induce high titre, this antibody and wild type mRBP4 cross reaction.Therefore, embodiment 2 has further supported the present invention to can be used as common method relevant or other the weak immunogenic effective immunization therapy therapy of cancer that creates antagonism.
Active immunotherapy is surpassing forward position (Waldmann, the T.A. (2003) " immunotherapy: the past, present and following " (Immunotherapy:past, present and future) that all is in prophylaxis against infection diseases twoth century and makes great efforts Nat Med9:269-277).Yet the ability reduction that immune system starts to reply for the strong immunization of autoantigen makes generation difficult more at the treatment vaccine of cancer or chronic degenerative diseases.Recently, we show with the immunogenicity alpha-non-natural amino acid mix autologous protein provide the simple effective method that overcomes immunologic tolerance (referring to Grunewald, J. etc. (2008) " immunochemistry termination self-tolerance " (Immunochemical termination of self-tolerance) Proc Natl Acad Sci U S A105:11276-11280 and embodiment 1).We have characterized the characteristic and the persistence of polyclone IgG antibody response herein, and begin to establish pNO 2The generality of the inductive self tolerance forfeiture of Phe-.With a plurality of surface residue independent mutations of Mus tumor necrosis factor-alpha (mTNF α) is right-Nitrobenzol alanine (pNO 2Phe) caused the polyclone of T cell-dependence and continue anti--mTNF α IgG autoantibody and reply and continued at least 40 weeks.Antibodies is a plurality of epi-positions on mTNF α, and the protection mice exempts from the inductive serious endotoxemia of lipopolysaccharide (LPS) stimulation.With Mus retinol binding protein matter (RBP4) pNO 2Phe 43The muton immune mouse also shows the IgG antibody response that can induce high titre, this antibody and wild type mRBP4 cross reaction.These discoveries show that this may be to produce effectively antagonism cancer conventional method relevant or the antigenic immunotherapy of immunogenicity a little less than other.
The key of immunity identification self-non-self process is self-tolerance (Goodnow (2007) " a plurality of steps of autoimmune disease morbidity " (Multistep pathogenesis of autoimmune disease) Cell 130:25-35), wherein mammiferous immune system produces " tolerance " to avoid autoimmune disease for oneself protein, mainly is because autoreaction B-or T-cell lack or inactivation.Yet, but known many years ago induction of immunity system attack oneself protein matter.For example, can induce cross reaction immunne response (Dalum etc. (1999), " immune induction is to the therapeutic antibodies of anti-TNF alpha " (Therapeutic antibodies elicited by immunization against TNF-alpha) by in chimeric antigen, introducing external t helper cell epi-position for oneself protein matter Nat Biotechnol17:666-669, Zuany-Amorim etc. (2004) " Auto Vac TNF106 induces the generation of TNF α autoantibody: the new method of treatment anaphylactic disease " (Induction of TNF-alpha autoantibody production by AutoVac TNF 106:a novel therapeutic approach for the treatment of allergic diseases) Int Arch Allergy Immunol133:154-163) by extensive chemical derivatization (Weigle to autoantigen, W.O. (1965), " autoimmune of inducing rabbit after the homology Elityran injection of allos or change " (The Induction of Autoimmunity in Rabbits Following Injection of Heterologous or Altered Homologous Thyroglobulin) J Exp Med121:289-308), or by dna vaccination (Leitner etc. (2003), " activate inherent antiviral path based on the dna vaccination of α virus and break immunologic tolerance " (Alphavirus-based DNA vaccine breaks immunological tolerance by activating innate antiviral Pathways) Nat Med9:33-39).In addition, the specific gene and the cell mechanism of multiple participation self tolerance have been identified, destroy them and will break tolerance and autoimmune disease (Goodnow (2007), " a plurality of steps that immunological diseases take place " (Multistep pathogenesis of autoimmune disease) Cell130:25-35; Hill etc. (2008), " progress on autoimmune disease hereditism basis " (Recent acquisitions on the genetic basis of autoimmune disease) Front Biosci13:4838-4851).Although obtained these progress, but the process that designs effective immunotherapy is still slow, such as only there being minority treatment of cancer vaccine to be in (Small etc. (the 2006) " transitivity in late period of clinical development, asymptomatic, the III phase immunization therapy experiment that the placebo that uses sipuleucel-T (APC8015) to carry out among the intractable carcinoma of prostate patient of hormone is controlled " (Placebo controlled phase III trial of immunologic therapy with sipuleucel-T (APC8015) in patients with metastatic, asymptomatic hormone refractory prostate cancer) J Clin Oncol24:3089-3094; Schlom etc. (2007), " vaccine therapy of cancer: biology and put into practice " (Role of vaccine therapy in cancer:biology and practice) Curr Oncol14:238-245).
The nitro aryl has hyperimmunization originality, may be because it forms powerful piling up and the interactional ability of Van der Waals.In fact, the non-specific derivatization from the body cancer cell that contains the dinitro benzene group is used as vaccine (Berd, D. (2004) " M-Vax:an autologous, hapten-modified vaccine for human cancer " in the melanomatosis people Expert Rev Vaccines3:521-527), and the formation of 3 '-nitrotyrosine participates in the pathology of various autoimmune disease (Aulak etc. (2001), " protein group method identify in the inflammatory stimulus process in the body nitrated protein " (Proteomic method identifies proteins nitrated in vivo during inflammatory challenge) among the physiology Proc Natl Acad Sci U S A98:12056-12061; Pacher etc. (2007), " nitric oxide and peroxide nitroso-group anion and health and disease " (Nitric oxide and peroxynitrite in health and disease) Physiol Rev87:315-424; Hardy etc. (2008), " at TCR or MHC contact position tyrosine is converted into inflammation related analogs 3 '-nitrotyrosine and can fully affects cd8 t cell to the identification of the restrictive lymphocytic choriomeningitis virus glycoprotein antigen of MHC I class epi-position " (Conversion of tyrosine to the inflammation-associated analog 3 '-nitrotyrosine at either TCR-or MHC-contact positions can profoundly affect recognition of the MHC class I-restricted epitope of lymphocytic choriomeningitis virus glycoprotein 33 by CD 8T cells) J Immunol 180:5956-5962). Whether can be used for breaking tolerance for specific oneself protein matter in order to test this immunogenicity group, we at first introduce right-Nitrobenzol alanine (pNO in the single site of Mus TNF α2Phe) residue.Use genetic method that the Tyr86 of mTNF α is substituted by pNO2Phe, having strengthened the T cell help induces at the strong cross reacting antibody of disease association oneself protein matter and replys (Grunewald, J. etc. (2008), " immunochemistry of self tolerance stops " (Immunochemical termination of self-tolerance) Proc Natl Acad Sci U S A 105:11276-11280).Herein, we show that immunochemistry breaks self tolerance and cause that lasting high titre resists to reply, and effectively protect the stimulation of mice antagonism lipopolysaccharide (LPS).And, but we show this method vague generalization to the irrelevant oneself protein matter of immunologic function, retinol binding protein matter 4 (RBP4) by name.
PNO 2 Phe-induces the Mechanism Study of breaking self tolerance
We have shown and have used pNO before 2Phe replaces mTNF α Tyr86 to be caused at the cross reacting antibody of the proteinic high titre of wild type (WT) and replys.The demonstration mutain can be bred by inducing T cell in immune animal, although WT protein can not be induced (Grunewald, J. etc. (2008), " immunochemistry of self tolerance stops " (Immunochemical termination of self-tolerance) Proc Natl Acad Sci U S A 105:11276-11280).For antagonism pNO is provided 2More evidences of the immunne response that the T cell of Phe TNF α relies on, we are with anti--mice IgM or resist-and mice IgG second antibody is to carrying out mTNF α, and autoantibody carries out elisa assay.PNO 2Phe 86Anti-in the mTNF alpha immunization Bcl-2 mice serum-mTNF α autoantibody mainly is the IgG hypotype, shows the immunoglobulin class conversion (Figure 16 A) that T is cell-mediated.In order to determine pNO 2Whether the existence of Phe is important for whole immunologic process, and we at first use the pNO in the complete Freund's adjuvant (CFA) 2Phe 86MTNF α injects 4 mices, WT mTNF α or pNO in the full Freund adjuvant (IFA) that toos many or too much for use then 2Phe 86MTNF α carries out 7 injections.The result of Figure 20 clearlys show, with respect to pNO 2Phe 86The cross reactivity that mTNF α, WT mTNF α can not keep remarkable titre resists-the mTNF Alpha antibodies.This result has supported pNO 2The inductive self tolerance of Phe-needs this different viewpoint of t cell response of nitrobenzophenone mediation, and consistent with the research that can't induce strong immunization to reply about Tyr86Phe TNF α muton before.
A problem of inducing self tolerance to break related mechanism about pNO2Phe-is whether antibody response is at comprising pNO 2Whether the epi-position of Phe the epi-position expansion perhaps takes place, and causes that the polyclone IgG of a plurality of epi-positions in the antagonism target proteins matter replys.In order to answer this problem, use pNO 2Phe 86MTNF alpha immunization Bcl-2 mice produces 50 B cell hybridomas, and these clone the antibody of the WT mTNF α that whether creates antagonism through the ELISA Screening and Identification.We test these monoclonal antibodies (mAbs) and combining that three mTNF α fragments compositions are gathered then, these fragments are passed through escherichia coli expression, molecular weight is verified (Figure 21) through MALDI TOF: N-terminal fragment (aa 1-60), interior segments (aa 61-100) and C-terminal fragment (aa 101-156).Although this experiment on a large scale the family that at the linearity (supposition is successive) B cell epitope specificity, we have identified 5 mAb (3L24,5K19,6J22,7O1, and 7F23) be incorporated into the N-terminal fragment, 1 mAb (1P19) is incorporated into C-terminal fragment (Figure 22).Be not have mAbs significantly in conjunction with original immunogenic pNO 2Phe 86The coding interior segments.Therefore, pass through pNO 2Phe 86The mTNF alpha immunization produces in conjunction with the antibody more than an epi-position, and these epi-positions need not to comprise the pNO in the immunogen 2The Phe residue.From pNO 2Phe 86Polyclone IgG of mTNF alpha immunization mice and natural mTNF α cross reaction, the Kd value is at nanomole scope (Figure 16 B).In a word, these results have further supported by simply inserting pNO in oneself protein matter 2The Phe residue produces the hypothesis at the cross reaction neutralizing antibody of oneself protein matter.
PNO2Phe induces the persistence of antibody response
In order to determine the persistence of anti--mTNF α IgG antibody titer, we use pNO 2Phe 86Three Bcl-2 mices of mTNF alpha immunization.After stimulating injection the last time, get blood at the appointed time with the anti-pNO of elisa assay 2Phe 86MTNF α.Be that antibody horizontal maintains greater than 80% initial level, 40 weeks (Figure 16 C) at least at least, puts to death mice afterwards significantly.By contrast, one based on carrying out with the mTNF α that comprises the clear lysosome t cell epitope of ovum gallinaceum in the anti-mTNF α inoculation study of immunity before, the last 4 all backs titres that stimulate descend, mTNF Alpha antibodies titre has reduced 80-87% (Dalum etc. (1999), " anti-TFN alpha immunization inductive treatment antibody " (Therapeutic antibodies elicited by immunization against TNF-alpha) Nat Biotechnol 17:666-669) after 26 weeks.Therefore, we are based on pNO 2The vaccine scheme of Phe can effectively be induced lasting immunity and the generation long-term protection of antagonism as the TNF α of disease association autoantigen.
Sudden change is extended to other surface site of mTNF α
In order to check pNO 2The versatility of breaking of the inductive self tolerance of Phe sports pNO with other 4 surperficial exposed residues of mTNF α 2Phe:Lys 11, Gln 21, Asp 42And Val 49(Figure 23 A).The structure of these residues is also different with right-Nitrobenzol alanine.Confirm pNO at SDS-PAGE and mass spectrum 2Phe 11MTNF α, pNO 2Phe 21MTNF α, pNO 2Phe 42MTNF α and pNO 2Phe 49After the composition and homogeneity of mTNF α (Figure 23 B and table 3), the size exclusion chromatograph shows that proteinic quarternary structure is a trimer (table 4).And the experiment of NF κ B-luciferase reporter gene shows pNO 2Phe 11The mTNF alpha active be WTmTNF α 9%, pNO 2Phe 21The mTNF alpha active be WT mTNF α 22%, pNO 2Phe 42The mTNF alpha active is 22% and the pNO of WT mTNF α 2Phe 49The mTNF alpha active is 10% (table 4 and Figure 23 C) of WT mTNF α.Therefore the pNO that characterizes before the activity of all mutons is significantly higher than 2Phe 86MTNF α, it only is equivalent to wild-type protein active 2% in experiment.In order to measure pNO 2The immunogenicity of PhemTNF α muton, 14 C57BL/6 mices are divided into five groups and also inject these mutons or WT mTNF α respectively, used scheme is RIMMS (multidigit point repeats immunity) scheme (Kilpatrick etc. (1997), " using the RIMMS affine sophisticated monoclonal antibody of exploitation fast " (Rapid development of affinity matured monoclonal antibodies using RIMMS) Hybridoma16:381-389).Elisa assay shows that the mTNF alpha active in the experiment of NF κ B-luciferase reporter gene is irrelevant with the ability of inducing antibody response, has got rid of for immune direct influence.As shown in figure 17,11 pNO 2Phe induces the IgG of the high titre of antagonism WT mTNF α to reply, with antagonism pNO 2Phe 11The mTNF alpha immunization former quite.By contrast, although also having produced antagonism, 21,42 and 49 sudden change contains pNO 2The antigenic high titre IgG of Phe replys, but IgG antibody only produces faint cross reaction with WT mTNF α.The antibody that produces at four sudden change antibody TNF α is used for 40 C57BL/6 mices are carried out active immunity, and mice is divided into 5 groups at random, and with resisting-pNO 2Phe or anti--WT mTNF α IgG inject.Behind the active immunity 24 hours, stimulate animal (Niessen etc. (2008), " dendritic cell PAR1-S1P3 signal path is relevant with blood coagulation and inflammation " (Dendritic cell PAR1-S1P3 signalling couples coagulation and inflammation) Nature 452:654-658) with LPS as previously mentioned.Under the LPS of lethal dose stimulated, all accepted anti--pNO 2Phe 11The mice of mTNF α IgG all survive (Figure 18) even if. accept anti--pNO of moderate cross reaction 2Phe 21MTNF α IgG, anti--pNO 2Phe 42MTNF α IgG and anti--pNO 2Phe 49Other group of mTNF α IgG, survival rate also is at least 75%; Yet the survival rate of injecting anti--WTmTNF α IgG mice only is 13%.Therefore, use pNO 2The ability that Phethe breaks self tolerance does not depend on the single amino acid position, because we show that at least 5 positions (comprising 86) can induce anti--neutrality cross reaction that mTNF α IgG replys in vivo.And the replacement site need not the structural similarity with right-Nitrobenzol alanine.

Sudden change mRBP4 protein expression and sign
Since when a plurality of positions in the mTNF α are sported pNO 2Can break self tolerance during Phe, so we consider whether this method can be generalized to other oneself protein matter.Specifically, we have detected pNO 2Phe breaks the ability (Zanotti etc. (2004) of another serum oneself protein matter of antagonism RBP4 model self tolerance, " the blood plasma retinol binding protein: structure and with the interaction of retinol, vitamin A and thyroxine transport protein " (Plasma retinol-binding protein:structure and interactions with retinol, retinoids, and transthyretin) Vitam Horm 69:271-295; Raghu etc. (2004), " blood plasma retinol binding protein, the interaction of thyroxine transport protein and its part: in the balance of vitamin A, the influence of thyroxine transport protein amyloidosis " (Interactions amongst plasma retinol-binding protein, transthyretin and their ligands:implications in vitamin A homeostasis and transthyretin amyloidosis) Biochim Biophys Acta 1703:1-9).Compare with TNF α, this is the monomeric protein of highly solvable a, molecular weight relatively low (20kDa).The RBP4 knock-out mice does not show the unusual (Vogel etc. (2002) of phenotype except visual impairment, " retinol binding protein deficient mice: visually impaired biochemical basis " (Retinol-binding protein-deficient mice:biochemical basis for impaired vision) Biochemistry 41:15360-15368), show that mice can survive at self RBP4 and in the immunne response.X-ray crystal structure (Cowan etc. (1990) based on people's monomer RBP4, " with 2A resolution crystal refinement Retinol Binding Protein from Human Serum " (Crystallographic refinement of human serum retinol binding protein at 2A resolution) Proteins 8:44-61), we select to sport pNO as the lower surface exposed residue 2Phe:Tyr 43And Tyr 108(Figure 24).These residues are conservative at the mammiferous RBP4 camber of difference, comprise Mus RBP4 (mRBP4).These mRBP4 mutons and WT mRBP4 are expressed with the terminal His6-label protein of N-matter in escherichia coli, under the degeneration condition, use Ni2+ affinity chromatography purification, and carry out again folding (Greene etc. (2001) according to the previous experiments scheme, " the role of conserved residues in structure and stability: the tryptophan of Retinol Binding Protein from Human Serum, lipocalin protein superfamily model " (Role of conserved residues in structure and stability:tryptophans of human serum retinol-binding protein, a model for the lipocalin superfamily) Protein Sci 10:2301-2316).SDS-PAGE analyzes and to containing the Trypsin enzymolysis MS/MS fragmentation of alpha-non-natural amino acid, has confirmed pNO 243 and 108 sites (Figure 24,25 and 27) that the Phe fixed point is mixed mRBP4.Analytical type size exclusion chromatograph shows that all mRBP4 protein are monomer structure, this and the quarternary structure consistent (table 5) (Cowan etc. (1990), " with 2A resolution crystal refinement Retinol Binding Protein from Human Serum " (Crystallographic refinement of human serum retinol binding protein at 2A resolution) Proteins 8:44-61) of the people RBP4 that has delivered.And, replace experiment, all pNO according to retinol 2The bonded Kd value of PhemRBP4 muton and retinol is in the nanomole scope, this and WT mRBP4 very consistent (table 5).

PNO 2 Phe-induces the versatility of breaking self tolerance
In order to detect pNO 2The immunogenicity of Phe mRBP4 muton is divided into 4 groups at random with 12 Bcl2 mices, according to RIMMS scheme pNO 2Phe 43MRBP4, pNO 2Phe 108MRBP4 and WT mRBP4 injection.(referring to (1997) such as Kilpatrick, " using the RIMMS affine ripe monoclonal antibody of exploitation fast " (Rapid development of affinity matured monoclonal antibodies using RIMMS) Hybridoma 16:381-389).According to elisa assay, with WT mRBP4 or pNO 2Phe 108The do not create antagonism remarkable serum IgG titre (Figure 19 A) of WT mRBP4 of mRBP4 mice immunized.By contrast, use pNO 2Phe 43The mRBP4 mice immunized shows significantly high serum IgG titre (until 1: 100,000), with pNO 2Phe 43MRBP4 immunogen and wild-type protein all produce combination.Use the C57BL/6 mice to obtain analog result (Figure 26).And, according to using pNO before 2Phe 86PNO is used in the observation of mTNF α 2Phe 43MRBP4 protein carries out immune induction pNO 2Phe 43MRBP4 specific C D4 +The T cell shows the immunne response (Figure 19 B) of mature T cells-dependence.In a word, these results have further supported to introduce pNO in protein sequence 2Phe creates strong t cell epitope, thereby initial persistence is intersected the hypothesis of reflection IgG antibody response.Be not that all sites all cause strong cross reactivity immunne response, this is not astonishing, because can not all corresponding potential t cell epitope of all sites.
We introduce pNO with genetic method at demonstration 2Phe causes lasting antagonism oneself protein matter mTNF α and the IgG antibody response of mRBP4.The mechanism aspect mixes in single site that right-nitrobenzophenone obtains being stimulated by the pNO2Phe muton and the T cell that can not be stimulated by WT albumen.This pNO 2The inductive T cell of Phe relies on replys the activation that finally causes self-activation B cell and the polyclonal antibody of generation and the cross reaction of natural oneself protein matter height.These results and the research that recently can strengthen t cell response about post translational modification protein be comparability (Cantaert etc. (2006), " citrulline albumen is at rheumatoid arthritis: key ... but not enough! " (Citrullinated proteins in rheumatoid arthritis:crucial ... but not sufficient! ) Arthritis Rheum 54:3381-3389; Backlund etc., (2002) " the saccharifying antigen of selection advantage T cell-specific type in humanized transgenic mice and the rheumatoid arthritis, (263-270) ", (Predominant selection of T cells specific for the glycosylated collagen type II epitope, (263-270) in humanized transgenic mice and in rheumatoid arthritis) Proc Natl Acad Sci U S A 99:9960-9965; Dzhambazov etc. (2005), " the main t cell epitope on the II collagen type in normal cartilage by glycosylation, but in rat and human arthritis, modified " (The major T cell epitope on type II collagen is glycosylated in normal cartilage but modified by arthritis in both rats and humans) Eur J Immunol 35:357-366).For example, citrullineization and glycosylation be post translational modification related in the T cell dependency autoimmune disease (Cantaert etc. (2006), " citrulline albumen is at rheumatoid arthritis: key ... but not enough! " (Citrullinated proteins in rheumatoid arthritis:crucial ... but not sufficient! ) Arthritis Rheum 54:3381-3389; Backlund etc., (2002) " the saccharifying antigen of selection advantage T cell-specific type in humanized transgenic mice and the rheumatoid arthritis, (263-270) ", (Predominant selection of T cells specific for the glycosylated collagen type II epitope, (263-270) in humanized transgenic mice and in rheumatoid arthritis) Proc Natl Acad Sci U S A 99:9960-9965; Dzhambazov etc. (2005), " the main t cell epitope on the II collagen type in normal cartilage by glycosylation, but in rat and human arthritis, modified " (The major T cell epitope on type II collagen is glycosylated in normal cartilage but modified by arthritis in both rats and humans) Eur J Immunol 35:357-366).357-366; Zhang etc. (2008), " in the rheumatoid arthritis to the proteic immunity of citrullineization " (Immunity to citrullinated proteins in rheumatoid arthritis) Annu Rev Immunol 26:651-675; Sollid, L.M. (2000), " molecular basis of celiac disease " (Molecular basis of celiac disease) Annu Rev Immunol 18:53-81).Similar, the dinitrofluorobenzene of dermatogen is modified as the t cell response model of allergy contact and has been used many decades (Toews etc. (1980) " whether the decision of epidermis youth Ge Hansi cell density vomits contact allergy or bradykinesia after dyeing with DNFB skin " (Epidermal Langerhans cell density determines whether contact hypersensitivity or unresponsiveness follows skin painting with DNFB) J Immunol 124:445-453).Therefore with pNO 2Phe fixed point is mixed oneself protein matter and has been set up a simple model system by behind the biochemical method mock translation or the self tolerance forfeiture of chemistry mediation.Therefore this method helps also to understand how immune system produces immunne response to chemical modification antigen in self-immunprocess.And, pNO 2The inductive self tolerance of Phe break not only effective ways as the neutralizing antibody of the rational oneself protein matter of cancer or degenerative disease related diseases that creates antagonism, also can be applicable to the weak immunity exotic antigen of infectious agent.

Immunity also produces monoclonal antibody (mAb)
The WT of purification or pNO 2Phe mTNF α produces anti--mTNF Alpha antibodies as immunogen.Use RIMMS scheme immunity Bcl-2 transgenic mice (C57BL/6-TgN (BCL2) 22Wehi) or C57BL/6 mice.(referring to (1997) such as Kilpatrick, " using the RIMMS affine ripe monoclonal antibody of exploitation fast " (Rapid development of affinity matured monoclonal antibodies using RIMMS) Hybridoma 16:381-389).The Bcl-2 transgenic mice shows the B cells survival and prolongs and the folliculus lymphocytic hyperplasia, makes it especially be fit to immunity.Simply say 18 days mice is carried out 8 injections.In the per injection, contain the proteinic 200 μ l PBS of 5 μ g and mix (as injection first) with complete Freund's adjuvant (CFA) at 1: 1, or mix (injection that is used to be left) at 1: 1 with incomplete Freund's adjuvant (IFA).Around all 6 the characteristic sites of periphery lymph node (PLN), carry out the immunogen injection.Carrying out injection same day the 8th time, collect test blood, use the elisa assay serum antibody titer.Collection and separation are from the PLN of high serum titer mice.With 50%PEG 1500 isolating lymphocyte and F0 murine myeloma cell are merged.With the cell seeding that merges in 384-hole tissue culturing plate.In hypoxanthine aminopterin thymidine (HAT) culture medium, select hybridoma, and screen anti-WT mTNF α with ELISA.
Result's explanation shown in embodiment 2 relevant drawings.
Figure 16 has shown mensuration pNO 2Phe 86Whether the mTNF alpha immunization promotes that type conversion is that IgG replys.IgG replys with WT mTNF α and produces remarkable cross reactivity in the demonstration mice, and continues at least 40 weeks.Figure 16 A exists in 17 days that remain injection in the initial injection that has complete Freund's adjuvant (CFA) and at incomplete Freund's adjuvant (IFA) and to measure pNO 2Phe 86The serum titer of the Bcl-2 mice of mTNF α or WT mTNF alpha immunization.As second antibody, measure anti-WTmTNF α with anti-mice IgM (first and second posts of each group of four posts) or anti-mice IgG (third and fourth post of each group of four posts) by ELISA.Before the measurement, with PBS buffer 1/100 (first and the 3rd post) or 1/1,000 (second and the 4th post) dilute serum sample of containing 1%BSA.Figure 16 B has shown the ELISA titration results, with polyclone anti--WT mTNF α IgG (inverted triangle) and polyclone resist-pNO 2Phe 86MTNF α IgG (diamond) is to pNO 2Phe 86The affinity of mTNF α or WT mTNF α quantizes.Figure 16 C has shown pNO 2Phe 86The persistence of serum titer in three Bcl-2 mices of mTNF alpha immunization.Order pNO 2Phe 86After mTNF α carries out 8 immunity, get blood at the appointed time and carry out anti-pNO 20 times 2Phe 86Elisa assay (the corresponding last immunity of t and get time between the blood).Before each the measurement, with 1: the 100 dilute serum sample of PBS buffer that contains 1%BSA.First of every group of 7 posts is before getting blood, and second is t=19 week, and the 3rd is t=23 week, and the 4th is t=28 week, and the 5th is t=32 week, and the six roots of sensation is t=36 week, and the 7th is t=40 week.
Other mTNF α surface exposed sites also has significant immunogenicity.In Figure 17 A, shown pNO 2Phe 11Anti-WT mTNF α (one on the left side of every coupled columns) in mTNF α or the WT mTNF alpha immunization C57BL/6 mice, pNO 2Phe 11The serum titer of mTNF α (one on the right of the 3rd, 4,5 coupled columns) and PBS (one on the right of 1,2 coupled columns).In Figure 17 B, shown pNO 2Phe 21Anti-WT mTNF α (one on the left side of every coupled columns) in mTNF α or the WTmTNF alpha immunization C57BL/6 mice, pNO 2Phe 21The serum titer of mTNF α (one on the right of the 6th, 7,8 coupled columns) and PBS (one on the right of 1,2 coupled columns).In Figure 17 C, shown pNO 2Phe 42Anti-WT mTNF α (one on the left side of every coupled columns) in mTNF α or the WT mTNF alpha immunization C57BL/6 mice, pNO 2Phe 42The serum titer of mTNF α (one on the right of the 9th, 10,11 coupled columns) and PBS (one of the mutation of 1,2 coupled columns).In Figure 17 D, shown pNO 2Phe 49Anti-WT mTNF α (one on the left side of every coupled columns) in mTNF α or the WT mTNF alpha immunization C57BL/6 mice, pNO 2Phe 49The serum titer of mTNF α (one on the right of the 12nd, 13,14 coupled columns) and PBS (one of the mutation of 1,2 coupled columns).Use the PBS buffer dilute serum sample (17A) 1/800 that contains 1%BSA before each the measurement; (17B) 1/200; (17C) 1/200; Or (17D) 1/200.
The result shows 11 pNO 2Phe induces the IgG of the high titre of antagonism WT mTNF α to reply, with antagonism pNO 2Phe 11The mTNF alpha immunization former quite.By contrast, although also having produced antagonism, 21,42 and 49 sudden change contains pNO 2The antigenic high titre IgG of Phe replys, but IgG antibody only produces faint cross reaction with WTmTNF α.
Figure 18 has shown that lipopolysaccharide (LPS) stimulates the various pNO in back 2Phe mTNF α muton immune mouse is survived benefited significantly.In Figure 18 A, LPS stimulates the previous day, uses from pNO 2Phe 11MTNF α and pNO 2Phe 49The IgG purification 4mg/kg of mTNF alpha immunization mice carries out peritoneal injection to male C57BL/6 mice.In Figure 18 B, LPS stimulates the previous day, uses from pNO 2Phe 21MTNF α and pNO 2Phe 42The IgG purification 4mg/kg of mTNF alpha immunization mice carries out peritoneal injection to mice.The mice that these mices are injected contrast IgG relatively carries out Kaplan-Meier survival curve mapping (n=8 group).Logarithm rank tests Jia Bangfeiluoni proofreaies and correct (Bonferroni correction) and analyzes as can be known, and each modifies survival advantage relative comparison group p<0.01 of TNF mice immunized.
